Fun fact, 12 million hectares of land of used to produce corn used for ethanol which is used to produce gas. I'll let you draw the conclusion. https://news.cornell.edu/stories/2025/04/trading-some-corn-e...

Yeah, the technology connections video on this was fantastic. If one was to cover that land in solar, you’d produce far more than the current energy demands of the US. Relying on an energy source which requires constant, continuous resource extraction is fucking stupid when we can spend resources up front and get reliable energy (solar + battery) for decades with minimal operating cost & maintenance. And then we’ll h…
Try not to blame anyone. Do it rationally if you can, from your message I understand your opinion.
I say this as a person that has lived in a developing country the last 15 years. It is not that simple IMHO...
The article is just wrong. And only mentions energy used for heating in passing. Heating requires MASSIVE amounts of energy. I should know bc I have a whole house battery and solar system (almost 30 kWh battery and 24kW solar). It keeps the lights on, but not heating. I live in a mild climate. The reality is that battery/solar requires major quality of life and activity time shifting trade-offs.
I live in a northern climate and I know multiple people who are net zero with solar+basic battery. Proper insulation and good windows go a very long way. For instance, I set my heat to 66F during the day and 60F at night. When I wake up in the morning, the register is usually still above 60F.
Earlier quoted context omitted.
What? They store the surplus in their batteries during the day and use it at night. I genuinely do not understand why people are so afraid of solar. It's baffling.
They've fallen victim to a catastrophically easy scare tactic, unfortunately. "The sun only shines during the day therefore solar is bad!" Dumb, but easy.
But to be clear, it's less about night vs day and more about summer vs winter.

66F is ridiculously cold to me, and I live in Canada where it can reach -40(F or C) in the winter. I would find that very uncomfortable and elderly people would be shivering constantly and highly susceptible to respiratory illness. I have a modern cold climate air source heat pump which essentially needs to run 24 hours a day to maintain a stable 20C when the outdoor temperatures reach -15C. Below that, the heat pump…
Yeah, I understand I'm probably an outlier at 66F. I was using the numbers more to point out how little a house temperature will drop with good windows and insulation.

Beyond the other better insulation comments, pairing electric with heat pumps that are SEER 10+ goes a long way to improve heating efficiency. Old resistive heaters are 1:1 on energy to heat, while newer heat pumps operate to much lower temperatures, and give you 1:10 or 1:15 electric:heat energy ratios.

At 66 degrees F? That sounds like put a sweater on if you’re chilly, not some near death extreme.
Any evidence that such an ‘extreme’ would cause issues?
By 2050 is the important caveat. That's assuming constant production of batteries at the current scale and production. It also assumes we figure out how to economically recycle materials from batteries (and total recovery may never be possible). Grid scale lithium batteries have an effective lifecycle of 15 years. In this potential future, global lithium reserves would actually start getting choked up before the 2050…
Obviously other energy sources are going to exist and non solar power will be produced, but nuclear is getting fucked in a solar + battery heavy future. Nuclear already needs massive subsidies and those subsidies will need to get increasingly large to keep existing nuclear around let alone convince companies to build more.
